PENCIL-SHARPENER.

Specification'of Letters Patent.

' Patented .Dec. 31, 1907.

Application filed March 22.1907. Serial No. 363.990.

To all whom it may concern:

Be it known that I, WILLIAM F. HERDRIoH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pencil-Sharpeners, of which the following is a specification.

The object of the present invention is to construct a pencil sharpener which shall be strong and compact and at the same time so formed that it can be stamped or died from a blank of sheet metal, thereby enabling the device to be manufactured at small cost and in an easy and convenient manner.

The pencil sharpener is intended to be carried in the'pocket and is adapted to be operated by the thumb and finger of one hand, leaving the other hand free for the manipulation of the pencil during the sharpening operation.

The invention relates to the construction of the several parts of the sharpenerand to the manner of assembling the same and to' thefeatures of construction. and combination of parts hereinafter described and claimed.

in. the drawings, Figure 1 is a side elevation of the open side of the sharpener; Fig. 2 a side elevation taken at right angles to the view of Fig. 1'; Fig. 3 a cross sectional. view taken on the line 3 3 of Fig. 1 with the cutter removed; F ig. 4 a similar View taken on line 4- of Fig. l; and Fig. 5 a similar view taken on line 5-5 of F ig. 1.

The pencil sharpener comprises a body 6 of tapered format-ion, h e vin in its front side a tapered opening 7. The body terminates at its upper end in a tubular neck 8 of suitable size'to receive the pencil, and the body terminates at its lower or tapered end in a flared base 9 adapted to receive the thumb of the user. The body has secured thereto,

at one side of the tapered opening and in alincment with the slope of the opening, a tubular guideway 10 which has slidably mounted therein a knife blade 11' which bears against the edges of the opening 7 and extends outwardly from and in transverse relation to the tubular guideway, as best shown in Fig. 1. The knife-blade has upwhich terminates at its upper end in a finger piece 1.3 adapted to be engaged by the first hooked over the openu'pper lip of the tubu- ....5a wardl v, extending therefrom a shank 12 lar guideway, the s ring being connected with the knife and a apted to raise the same after each depression of the finger piece.

The body portion, neck, base and tubular guideway are formed in two sections which are blanked or stamped from a piece of sheet metal and afterwards secured to ether to ive the intended information. heneck, ody, base and guideway comprise front sections 16, 17, 18, and 19, respectively, and rear sections 20, 21, 22, and 23, respectively. The edge of the front section is cut away to provide the opening 7 and the front section, above the opening, is provided with a tongue 24 which connects the front section 16 of the neck with the front section of the tubular guideway, and the tongue 24 abuts against and is secured to a sinnlar tongue 25 which connects the rear section 21 of the neck with the rear section of the tubular guideway.

The tongues are secured together by means posite edges of the front and rear sections of the neck are likewise provided with. ton ues 27 and 28, respectively, which are secure together by means of a rivet29. This mode of attaching the parts together holds the contacting edges of the front and rear sections of the device in alinement with one another. In like manner the front section 9 of the base is provided with a tongue 30 which connects the base with the lower end of the front sec.- tion of the tubular guideway, and the tongue 30 cooperates with a similar tongue 31 which connects the rear section 22 of thebase with 1 the rear section 23 of the tubular guideway, the two tongues being secured together by means of a rivet 32. The inner edges of the front and rear sections of the tubular ideway are flared or extended to form lips 33 suitably spaced to provide for the reciprocation of the knife blade 11, and at the same time provide a re-inforcement for the blade,

whereby it will be prevented from turning or wabbling. It is preferred to form the tubular guideway in substantially parallel relation with the farther edge of the opening 7, so that, as the knife travels up and own, its outer end will at all times rest upon the farther edge of the opening 7 and this operation, at a slight angle with respect to the projection of the pencil inserted through the neck, serves to, give a slight shearing movement to the knife, whereby the cutting oper- The other and of the user will be free to turn the pencil from time to time during the sharpening operation, which is performed by pressing down the operatin rod of the knife, thus shearing or cuttin 0% so much of the pencil as projects out of the opening 7. As the sharpening progresses, the encil will travel deeper and deeper into tfie tapered portion of the device, and the knife can be carried downfarther and farther until the pencil is com letely sharpened. The operation is one W 'ch is intended to thoroughly 7 shar en a pencil without breaking the lead,

- strong and rigid,

whic is usually brokenin attempting to'use pencil sharpeners of the turning variety.

By forming the parts in the manner indicated, the cost, of the article will be reduced to a minimum, since the entire sharpener, with the exce tion of the knife and spring, can he died or blanked out of a piece of sheet metal and the parts thereafter secured together in a very easy and rapid manner. The knife and shank can be made from a steel rod, the knife blade being beaten or flattened and thereafter tempered and sharpened, which enables a very good quality of steel to be employed in the sharpener, and at the same time enables the knives to be made in a cheap and easy manner. The de vice as a whole is extremely sim le and at the same timemay be made t oroughly and these characteristics, in

addition to the cheapness of cost, render the 'device'suitable as an advertising novelty. What I regard as new and desire to secure by Letters Patent is:
